PROBLEM TO BE SOLVED: To provide a manufacturing method for a reliable laminated piezoelectric body, with a cost suppressed while corresponding to application, by forming an even ceramics coating layer at a part where the end surface of an internal electrode layer of the laminated piezoelectric body is exposed. SOLUTION: A laminated piezoelectric body 1 has a structure where a piezoelectric ceramics layer 2 and internal electrode layer 3 are alternately laminated by plural numbers, with the end surface of internal electrode layer 3 exposed on the side surface, etc. Here, after a green sheet comprising piezoelectric ceramics and the internal electrode layer 3 are alternately laminated by plural numbers to form a green sheet laminated body of a specified shape, its outside surface is coated with ceramics, and de-binding and sintering are performed so that a ceramics coating layer 4 is formed at a part where the end surface of internal electrode layer 3 is exposed. The ceramics coating layer 4 is formed by a method suitable for required characteristics. |
